[CIR] Fix CIR tests by adding a triple/Requires. (#222346)
Now that we're trying to build by default, we actually have to be able
to build on other buildbots! But since we still don't have the
ABI/target stuff for non linux, we need to make sure our tests don't hit
that. Tests that execute 'clang' in some way are given a triple, ones
that are on .cir files we just add a 'requires'. Some day we should be
able to remove those, but it'll require us to add the cxxabi/etc for
windows.

[Clang][OpenACC] Fixed getExtValue Call on Invalid Gang Dim (#221502)
**Problem**
When an invalid 'gang dim' value is used in `CheckGangDimExpr`, the
function prints the value into the diagnostic message by calling
`getExtValue`. This function asserts on values that can't fit into a
signed integer.
**Solution**
`APSInt` has a `<<` operator anyway so just use that.
The fix causes the message to print with the following formatting:
```
test.cpp:5:40: error: argument to 'gang' clause dimension must be 1, 2, or 3: evaluated to 18'446'744'073'709'551'574
5 | #pragma acc routine(S::foo) gang(dim : S::foo())
| ^
1 warning and 1 error generated.
```
Fixes #221418

[clang] Warn on signed char array constant conversion (#203792)
This resolves #181730: fixes a missing `-Wconstant-conversion`
diagnostic for `signed char` array initialization.
Before this change, Clang warned for `signed char foo = 255;` but did
not
warn for `signed char bar[] = {255};`.
The warning suppression helper did not distinguish between `char`,
`unsigned char`, and `signed char` in brace-initialized arrays. Now it
does.

Log Message:
-----------
[SPIRV] Fix inconsistent operand order for counter resource intrinsic (#221646)
The `llvm.spv.resource.handlefrombinding` intrinsic stores its binding
operands in the order (DescriptorSet, BindingNo, ...). The
`llvm.spv.resource.counterhandlefrombinding` intrinsic should use the
same order.
The `llvm.spv.resource.counterhandlefrombinding` intrinsic is currently
emitted only by the `SPIRVLegalizeImplicitBinding` pass. The pass
previously built its operands in the wrong order, and the instruction
selector repeated the same inversion when emitting decorations.
This change makes the operand order consistent with
`llvm.spv.resource.handlefrombinding`.
Test update closes a coverage gap - there were no tests for explicit
`llvm.spv.resource.counterhandlefrombinding` calls.

[AMDGPU] Add missing attributes to llvm.amdgcn.init.whole.wave (#222493)
`llvm.amdgcn.init.whole.wave` only sets the EXEC mask and reports
whether the lane was active on entry. It never calls into the module,
never frees memory, and always returns, so it can carry `nocallback`,
`nofree`, and `willreturn`.
The neighboring `llvm.amdgcn.init.exec` and
`llvm.amdgcn.init.exec.from.input` already have all three; this brings
`init.whole.wave` in line and lets the attributor propagate them to
callers.

[CIR] Add offload container attribute (#206576)
Introduce `cir.offload.container`, a CIR dialect unit attribute that marks an
MLIR module as holding a host CIR module and its associated device CIR
modules in one IR unit while later offload merge/split pipeline passes need
visibility into both sides.
The marked module's body holds nested `builtin.module` operations. Each
nested module is tagged with `cir.offload.kind`, represented by the new
`#cir.offload_kind<host>` / `#cir.offload_kind<device>` enum attribute.
The structural contract expected by the follow-up pipeline work is
enforced in `CIRDialect::verifyOperationAttribute`, following the
`gpu.container_module` precedent:
* `cir.offload.container` is a unit attribute attached to a
`builtin.module`
* the first nested module is the host module
* all following nested modules are device modules
* the body contains only nested `builtin.module` operations
* at least one device module is present
* `cir.offload.kind` is only ever attached to a `builtin.module`
This patch only introduces the IR representation and verifier tests. The
passes that create, consume, or split this container are left to follow-up
patches.

[Clang] Avoid unnecessary overload resolution when building RecoveryExpr (#222296)
When overload resolution fails, we tried RecoveryCallExpr which
ended up performing duplicate overload resolutions, where the template
argument deduction can be expensive.
This patch removes those 'known' invalid overload candidates before
RecoveryCallExpr.

[CodeGen] Skip pseudo instructions in AggressiveAntiDepBreaker (#222271)
`ScheduleDAGInstrs` does not create SUnits for debug or pseudo
instructions. The aggressive anti-dependency breaker only skipped debug
instructions, so encountering a pseudo such as `PSEUDO_PROBE`
dereferenced a null SUnit.
Skip both debug and pseudo instructions and add a Hexagon regression
covering the existing aggressive anti-dependency path with legacy and
new machine pass managers.
Split from #221984 in response to review.

Adds Flang lowering, and LLVM IR translation for the OpenMP 6.0 `threadset` clause (spec 14.8) on `task` and `taskloop`.
- Add a `ThreadsetPolicy` enum (`omp_pool`/`omp_team`) and clause on `omp.task` and `omp.taskloop.context`, lowered from Flang.
- Translate `threadset(omp_pool)` to the free-agent task flag (`0x80`); `omp_team` leaves it unset, matching clang.
- Add semantics, lowering, and translation tests.

[RegAllocFast] Give an undef tied use the register of its tied def (#222249)
X86TargetLowering::emitSetJmpShadowStackFix zeroes a register by
building an XOR whose two uses are undef reads of its own def (per
MachineOperand.h "... reading the same dont-care value"). Def processing
frees a def whose tied use is undef before the uses are allocated, so
allocVirtRegUndef() no longer finds the virtual register and takes the
head of the allocation order instead. -verify-machineinstrs would fail:
```
renamable $rcx = XOR64rr undef renamable $rax(tied-def 0), undef renamable $rax, implicit-def dead $eflags
*** Bad machine code: Tied physical registers must match. ***
```
Take the register from the tie, and rewrite the instruction's other
reads of the value with it so that they keep agreeing on one register.

[BOLT][AArch64][Android] Recover from dump failure instead of exit (#221292)
Embedded in Android app, failed assert() or reportError() during a BOLT
profile dump should not exit the host process. Install a recovery point
in __bolt_instr_data_dump(), so any failure can longjmp back, return a
non-zero value to caller, and set a flag so later dumps can be skipped.
Clang does not support __builtin_setjmp/longjmp for the AArch64 Android
target, so add a minimal hand-written setjmp/longjmp in sys_aarch64.h.
Since the majority Android apps run on AArch64 CPUs, while at this I
defined `ANDROID_AARCH64` and replaced `__ANDROID__` with it in the
instrumentation runtime code.

[BOLT][ICP] Use PC-relative instructions for x86 PIC binaries in ICP (#216587)
Currently, BOLT x86 ICP optimization inserts an immediate-to-register
comparison instruction, which forces the use of 32-bit signed (32S)
relocations due to ABI limitations. This behavior does not align well
with the conventions of PIC/PIE binaries and **makes it highly prone to
JITLink relocation overflow errors when dealing with large binaries.**
Therefore, this patch introduces an additional lea instruction for the
x86 architecture to leverage PC-relative (32PC) addressing. This change
is intended to apply by default to PIC binaries, or when specific
options are provided.

- llvm.nvvm.mbarrier.init with trailing immarg `layout` operand, and nvvm.mbarrier.init a matching `layout` attribute (default to 0) Layout 0 is the default in-memory layout and is emitted as a plain mbarrier.init; layout 1 is emitted as mbarrier.init.layout::v1.
- llvm.nvvm.mbarrier.check_layout / nvvm.mbarrier.check_layout, lowering to mbarrier.check_layout.layout::v{0,1}.
Only the layout::v1 form of mbarrier.init and mbarrier.check_layout require PTX ISA 9.3 and sm_90
llvm.nvvm.mbarrier.init{.shared } are also merged into a pointer-overloaded llvm.nvvm.mbarrier.init with calls to either older forms auto-upgraded
Please refer [PTX ISA](https://docs.nvidia.com/cuda/developer-preview/13.4/parallel-thread-execution/index.html)

[Lifetime Safety] Name operator calls in alias-chain diagnostics (#221803)
This updates Lifetime Safety alias-chain diagnostics to identify
overloaded operator and conversion calls instead of describing them
generically as an `expression`.
Previously, these calls were reported as `expression aliases the storage
of ...`, which could make it unclear which operation introduced the
alias. The diagnostic now reports the callee using the existing
diagnostic name printer, producing descriptions such as:
- `result of call to 'operator->'`
- `result of call to 'operator()'`
- `result of call to 'operator basic_string_view'`
Template arguments are preserved for operator function-template
specializations. For example:
- `result of call to 'operator+<const int>'`
- `result of call to 'operator-<__gnu_cxx::basic_iterator<const int>>'`
This makes each aliasing step explicit and identifies the particular
call responsible for propagating the alias.

[Windows] Don't export clang::interp symbols for plugins (#221295)
With `LLVM_EXPORT_SYMBOLS_FOR_PLUGINS=ON`, `clang.exe` built from the
23.x release branch exports 66679 symbols on x86_64 Windows, over the
65535 limit of the PE export table, so it no longer links:
```
lld-link: error: too many exported symbols (got 66679, max 65535)
```
For comparison, the same configuration on 22.1.8 exports 65465 symbols,
so the headroom was already almost gone.
`clang::interp`, the constant expression bytecode interpreter, accounts
for roughly 4500 of the exported symbols (counted with `llvm-readobj
--coff-exports` on a linked aarch64 23.1.0 `clang.exe`). Its headers
live in `clang/lib/AST/ByteCode` and are not installed; the only mention
in a public header is the forward declaration of `interp::Context` in
`ASTContext.h`. A plugin cannot call into it, so there is no reason to
keep exporting it. Filtering it out follows the existing
`dump`/`dumpColor`/`printPretty` exclusions in
`should_keep_microsoft_symbol`.
Related: #87865 (open; earlier rounds #60109, #56109). This does not get
the MSVC-with-examples configuration from that issue under the limit by
itself, but it removes the largest block of symbols that can never be
used by a plugin, and is what gets the Firefox clang 23 toolchain
(x86_64-pc-windows-msvc, X86;ARM;AArch64;WebAssembly,
clang+lld+clang-tools-extra) from 66679 to roughly 62100 exports.

[Windows] Export Registry<T> members and accessors for plugins again (#221296)
Since #185141 reworked `llvm::Registry`, the registered-node list lives
behind the explicitly specialized
`llvm::detail::getRegistryLinkListInstance<R>()` accessor defined by
`LLVM_DEFINE_REGISTRY`, and the `Head`/`Tail` static data members that
used to be referenced across objects are gone (#163391 had special-cased
those).
`extract_symbols.py` handles neither. The accessor is a `??$` function
template specialization, which the script drops on the assumption that
it can be instantiated in the importing translation unit; here it
cannot, it is defined once by `LLVM_DEFINE_REGISTRY`. And `Registry<T>`
members are only exported when some object references the `Registry`
template, which nothing does anymore because every use goes through the
accessor. On a static clang.exe built with
`LLVM_EXPORT_SYMBOLS_FOR_PLUGINS`, the export table went from 11
`Registry<clang::PluginASTAction>` symbols on 22.1.8 to zero on 23.1.0,
and linking a plugin fails:
```
lld-link: error: undefined symbol: __declspec(dllimport) public: static void __cdecl llvm::Registry<class clang::PluginASTAction>::add_node(class llvm::Registry<class clang::PluginASTAction>::node *)
>>> referenced by host_Registration.obj:(_GLOBAL__sub_I_Registration.cpp)
```
Keep the accessor specializations, and treat a reference to an accessor
as a reference to the `Registry` template so its explicitly instantiated
members are exported as they were before. Verified on the 23.1.0 static
libraries: `Registry<PluginASTAction>::add_node`, the node/iterator
members and the accessor come back for every registry (PluginASTAction,
PragmaHandler, GCStrategy, GCMetadataPrinter, ...), 141 symbols in total
in the Itanium run over the clang libraries. The `Head`/`Tail` rule from
#163391 no longer matches anything and is dropped.
Related: #163367 / #163391 (the previous Registry export fix), #87865.

and the fix was verified by running extract_symbols.py over the 23.1.0
clang static libraries (the Registry members and accessors come back)

[llvm-rc] Add /showIncludes dependency reporting (#217102)
Add `/showIncludes` support to `llvm-rc` so build systems can discover
the files a resource compile depends on. This enables Ninja and other
build systems to track and correctly recompile the `.rc` file when
inputs change.
Two kinds of dependencies are reported:
- Preprocessor header dependencies, by forwarding `--show-includes` to
the clang preprocessor.
- Resource files, (bitmaps, icons, manifests, etc) that are used in the
resource file.
The output format matches the `/showIncludes` format that cl.exe and
clang-cl.exe use, and that Ninja can consume natively via `deps=msvc`.

[clang][bytecode] Use opaque pointers for decl-based dummy pointers (#220917)
This uses the recently introduced opaque pointers for what we used to
use dummy pointers for, if the base of the pointer is a declaration.
This of course means we see opaque pointers in a lot more places.
However, we don't need to actually allocate anything for their data
anymore, resulting in a lot fewer allocations for such pointers.

[libc++][pstl] Implementation of parallel std::minmax_element() based on parallel reduce (#221572)
This PR adds an implementation of parallel `std::minmax_element()` based
on parallel reduce.
The implementation formulates `minmax_element` as a reduction of
iterators over the input range.
The iterators are first transformed into a min-max iterator pair.
The reduction is provided in two forms: 2-element reduction that makes
an iterator pair pointing to a smaller and a greater value, and a
range-based reduction with init value.
The latter delegates the heavy-lifting to the serial implementation of
`std::minmax_element()`.
Part of #99938.

[AMDGPU] Use new CSR cost calculation (#219220)
So far, AMDGPU backend relied on the legacy calculation for the cost of
the first use of a callee-save register. This legacy path scales the
entry block frequency by a fixed value, making a comparison with
alternatives, e.g., rematerialization, difficult due to different
scales. One example for that is the work in
https://github.com/llvm/llvm-project/pull/206756, where comparison of
rematerialization cost and first use of a CSR is hard to compare due to
the different scales.
Change to instead use the new calculation path with different target
hooks for better comparability.
As the new scale is different, the cost was changed. The new cost value
accounts for various factors impacting CSR cost.
This change (with different cost value) was originally part of
https://github.com/llvm/llvm-project/pull/202007. Another part of that
PR was already extracted into
https://github.com/llvm/llvm-project/pull/214857.

[AArch64][NEON] Fold insert(zero, extract(X, 0), 0) -> X when X is known to zero lanes 1-N (#213940)
Add patterns for NEON across-lane reductions whose scalar result
is inserted into lane zero of a zero vector.
This is valid because these instructions place their result in lane zero
and
clear the remaining lanes.
Limit this change to matching input and result vector types. Mixed
vector
sizes and scalar conversions are not part of this PR.
Handle llvm.vector.reduce.add.v2i64 separately because it lowers to
ADDP.
NEON has no equivalent instruction for v2i64 signed or unsigned min/max
reductions, so they cannot use this fold. Double-precision
floating-point
reductions are already handled by pairwise instruction patterns.

[orc-rt] Express CI symbols as C-level names (#222564)
Controller-interface wrapper functions are now declared extern "C",
exported, and registered under their C-level names, so that they resolve
identically whether looked up through the bootstrap symbol map or via
dlsym.
In addition to removing the inconsistency between the symbol-table and
dlsym names, making CI functions public declarations allows unit tests
to call CI wrappers directly (rather than having to resigster them and
then look them up in a symbol table).
ORC_RT_SPS_WRAPPER and ORC_RT_SPS_ALLOC_ACTION each split into _DECL and
_IMPL forms sharing a _SIG macro, giving the wrappers extern "C" linkage
and an ORC_RT_C_EXPORT annotation.
SimpleSymbolTable::addUnique now takes SymbolNameSpec names and mangles
them, with a second overload for merging one table into another.

[mlir-translate] Move InitLLVM ownership to the standalone tool (#222570)
Please Read: [RFC: Embeddable LLVM tool drivers for long-lived
hosts](https://discourse.llvm.org/t/rfc-embeddable-llvm-tool-drivers-for-long-lived-hosts/91754)
and [Why `InitLLVM` ownership matters section in the
RFC](https://discourse.llvm.org/t/rfc-embeddable-llvm-tool-drivers-for-long-lived-hosts/91754#p-367966-why-initllvm-ownership-matters-7)
`mlirTranslateMain` currently constructs `InitLLVM` internally. This is
fine when `mlir-translate` runs once as a standalone executable, but it
does not work for an in-process setting where the host remains alive and
invokes multiple LLVM tools. When `mlirTranslateMain` returns, the
`InitLLVM` destructor calls `llvm_shutdown()` and destroys
process-global `ManagedStatic` state that may still be needed by the
host and subsequent tool invocations.
[WasmBolt](https://github.com/anutosh491/WasmBolt) (try
[here](https://anutosh21.github.io/WasmBolt/)) is a concrete example of
such a host. It runs Clang, `mlir-opt`, `opt`, `llc` and LLD inside one
browser-hosted LLVM process, allowing users to inspect and transform
code without a remote compilation server.
As described in the [MLIR section of the
RFC](https://discourse.llvm.org/t/rfc-embeddable-llvm-tool-drivers-for-long-lived-hosts/91754#p-367966-mlir-13),
the real `mlir-opt` driver already works in this environment.
`MlirOptMain` does not own `InitLLVM`, so the surrounding host can
control the process lifetime. `mlirTranslateMain` does not currently
provide the same ownership boundary, which prevents us from integrating
it in the same clean way.
The working `mlir-opt` pipeline can be seen here:
https://www.youtube.com/watch?v=yga2lWelne4
This patch makes the two MLIR driver interfaces consistent by moving
`InitLLVM` from the reusable `mlirTranslateMain` entry point into the
standalone `mlir-translate` executable:
```text
standalone:
main -> InitLLVM -> mlirTranslateMain -> process exit
embedded:
host-owned InitLLVM / LLVMToolSession -> mlirTranslateMain
```
Standalone behaviour remains unchanged, while MLIRTranslateLib can now
borrow the process lifetime owned by a long-lived host.

[llc] Add a reusable LLVMLlcDriver library (#221896)
Please read :
[RFC](https://discourse.llvm.org/t/rfc-embeddable-llvm-tool-drivers-for-long-lived-hosts/91754)
and [RFC
section](https://discourse.llvm.org/t/rfc-embeddable-llvm-tool-drivers-for-long-lived-hosts/91754#p-367966-proposed-first-change-llvmllcdriver-8)
This splits `llc` into a small standalone executable and a reusable
`LLVMLlcDriver` library.
The change follows the structure introduced for `opt` by @wsmoses in
[#79205](https://github.com/llvm/llvm-project/pull/79205): the
command-line implementation moves into a driver library, while `llc.cpp`
remains the standalone entry point and continues to own `InitLLVM`.
The immediate motivation is embedding `llc` in long-lived applications
such as [WasmBolt](https://github.com/anutosh491/WasmBolt) (try
[here](https://anutosh21.github.io/WasmBolt/))
Currently, embedders must compile and modify a copy of `llc.cpp` because
the implementation and `main()` live in the same translation unit. This
split provides a reusable entry point without changing the behavior of
the
standalone `llc` executable.

In clang we have `--print-enabled-extensions` which will print the

useful to be able to print out the actual subtarget features for each
function, for debugging/testing purposes. Add an optimisation remark for
that.

IndexType is converted.
- using the original operands instead of the converted ops, creating

[MLGO] Gate model tests on optimization-specific lit features (#217906)
### Context
`have_mlir_lowering` only indicates that `LLVM_MLGO_MODELS` is
non-empty. It does not identify which model type was compiled.
### Motivation
An inliner-only configuration incorrectly enabled regalloc-specific test
commands, and vice versa.
### Changes
Add `have_mlir_lowering_inliner` and `have_mlir_lowering_regalloc` lit
features derived from the corresponding model-generation targets. Update
MLGO tests to use the appropriate model-specific feature, including GN
configuration defaults.
I leveraged AI to write this PR.

[opt] Move InitLLVM ownership to the standalone entry point (#222559)
Please Read: [RFC: Embeddable LLVM tool drivers for long-lived
hosts](https://discourse.llvm.org/t/rfc-embeddable-llvm-tool-drivers-for-long-lived-hosts/91754)
and [Why `InitLLVM` ownership matters section in the
RFC](https://discourse.llvm.org/t/rfc-embeddable-llvm-tool-drivers-for-long-lived-hosts/91754#p-367966-why-initllvm-ownership-matters-7)
`LLVMOptDriver` is already separated from the standalone `opt`
executable, but `optMain` currently constructs `InitLLVM` internally.
This means its destructor calls `llvm_shutdown()` whenever one driver
invocation finishes.
That is appropriate for a standalone executable, but not for a reusable
driver called by a long-lived host. For example,
[WasmBolt](https://github.com/anutosh491/WasmBolt) (try
[here](https://anutosh21.github.io/WasmBolt/)) invokes `opt`, `llc`,
Clang and LLD within one browser-hosted LLVM process and needs the LLVM
process state to remain alive between tool invocations.
This patch moves `InitLLVM` ownership into `opt.cpp`:
```text
standalone opt:
main -> InitLLVM -> optMain -> shutdown
embedded host:
host-owned InitLLVM / LLVMToolSession -> optMain
```
Standalone opt therefore keeps the same lifetime and behaviour, while
LLVMOptDriver can borrow the lifetime owned by an embedding application.
This patch is independent of the proposed `LLVMToolSession `and
`LLVMLlcDriver` changes that I've proposed in the RFC and can be
reviewed separately.

[OpenMP] Give the device shared memory allocations a debug location. (#221842)
Fixes https://github.com/llvm/llvm-project/issues/221831.
In generic mode on the device, the buffers that carry values into an
outlined region come from device shared memory rather than the stack, so
they are emitted as calls to `__kmpc_alloc_shared` and
`__kmpc_free_shared`. Those are definitions in the DeviceRTL, which
makes them inlinable calls, and the verifier requires an inlinable call
in a function with debug info to carry a !dbg location. None of these
calls had one, for two separate reasons.
1. `allocateVar()` and `deallocateVar()` took a bare insertion point, so
an override had no debug location to set on the runtime calls it emits
in place of the alloca the base class would have created. Fixed by
adding a `DebugLoc` parameter that carries one.
2. The `createOMPAllocShared `and `createOMPFreeShared` calls in
`createParallel` relied on the implicit conversion from an insertion
point to a `LocationDescription`, which selects the constructor that
leaves the debug location empty, and `updateToLocation` then installs
that empty location over whatever the builder had. Fixed by passing the
`Builder`, which carries the debug location along with the insertion
point. This is the same fix as #218961.

[JITLink][RISCV] Avoid quadratic removal of alignment edges (#222317)
We encountered this issue while using BOLT to instrument clang on
RISC-V. JITLink spent significant time removing alignment edges during
relaxation finalization in large code blocks with many alignment
relocations.
During RISC-V relaxation finalization, finalizeBlockRelax removes
AlignRelaxable edges individually from a block's edge vector. Each erase
shifts the remaining suffix, making this cleanup quadratic when the
number of alignment edges grows with the total edge count.
Compact surviving edges once and remove the trailing entries from the
back, preserving edge order and making cleanup linear. Count the
trailing entries before erasing to avoid comparing an invalidated
iterator.
These results support the performance benefit, but they come from
**GPT-generated** synthetic benchmarks and do not represent speedups on
real BOLT workloads.

[flang] add AllocationPolicy attribute to module and use it in InlineHLFIRCopy (#222013)
The StackArrays/AllocationPlacement pass cannot move fir.allocmem
created during InlineHLFIRCopy for the copy-in/cop-out buffers because
of there placement in branches.
Moving these allocmem outside of the branches is suboptimal as these
allocations may never occur at runtime (when the data is actually
already contiguous).
Extending the StackArrays pass is doable but very tedious (the data flow
analysis passes used in the pass cannot recognized "same
predicates"/understand that the two fir.if block that
allocate/deallocates will be both reached or never reached (even when
modifying InlineHLFIRCopy to use the same SSA value for both fir.if). So
this requires custom logic, and was adding 200 lines of non trivial code
to audit and I did not like it.
I decided to expose the allocation policy so that other passes can rely
on it. To make it the most flexible and future proof this is done via a
new module attribute instead of threading options in the driver to this
and that pass. This way, it will also be possible to have custom per
function policy if ever needed.
The InlineHLFIRCopy is updated to apply the small array threshold policy
(that decide when constant size arrays should always be placed on the
stack, regardless of the -fstack-array/-fno-stack-array). I also
increased this threshold from 64 to 1024 so that it cover my application
use case. This increase is in line with the industry practice (NV, IFX,
and gfortran will all allocate few Kb temporary copy-in/out buffers on
the stack, regardless of the optimization level). For now, I decided to
not apply the `-fstack-array` aspect as it is on by default with flang
and I want to measure the effect first before doing so (gfortran/ifx
also control dynamic copy-in/out buffer allocations with the stack-array
related flag, so there is a good chance we end-up doing it at some
point).

[mlir][vector] Fix mask neutral value for masked fmaximum/fminimum reductions (#222275)
Masked maximumf/minimumf reductions were lowered by replacing inactive
lanes with a neutral value before applying an unmasked reduction. The
maximumf neutral was incorrectly set to the negative subnormal closest
to zero, causing it to beat any negative active value. Similarly,
minimumf used FLT_MAX, which loses to an active +Inf.
This change adds LLVM dialect support for
llvm.vp.reduce.fmaximum/fminimum and lowers masked reductions directly
to these predicated intrinsics.

[libc] Optimize the GPU printf implementation with size hints (#222474)
Summary:
The GPU printf interface is functionally a shim to pass a `va_list` and
format string to the CPU for formatting. The size of the argument list
isn't exposed by the C ABI, but we can use `__builtin_object_size` to
try to look it up. This will bind to the `alloca` holding our arguments
in the ABI and return a positive size if it is known.
We do this opportunistically, as the check is lossy. In cases where it
is known, this saves a stack spill to store the true size. Additionally,
we can use this to detect cases where `printf` is being used as a simple
`puts`.
This saves 10 VGPRs for the `printf("string")` case. It also saves 8
bytes of stack in most all cases.

The implementation of `std::declval` calling `__declval` was originally

for `add_rvalue_reference`, which makes the old implementation faster
again, since we avoid instantiating any class types _and_ avoid overload
resolution.

[clang][CodeGen] Stop overriding GlobalVariable's default address space (#222367)
The `GlobalVariable` constructor used by `createGlobal` receives a
`std::optional<unsigned> AddressSpace` that, when unspecified, falls
back to `M.getDataLayout().getDefaultGlobalsAddressSpace()`. However,
`createGlobal`'s `AddressSpace` arg was a bare `unsigned` defaulting to
0. By doing that, it was effectively overriding the `GlobalVariable`'s
constructor fallback with 0. On targets whose default globals address
space is not 0 (AMDGPU, SPIR/SPIR-V), this emitted
`@llvm.global_ctors/dtors` in address space 0 causing some issues (see
https://github.com/ROCm/SPIRV-LLVM-Translator/issues/293).

[AArch64] Reorder ZPR stack spills to maximize ld1b/st1b pairings (#218950)
Currently, the stack allocation algorithm can order spilled ZPR
callee-saves in a way that prevents pairing.
Reorder ZPR callee-saves before frame indices are assigned to maximize
pairing opportunities. Pairing requires consecutive even/odd registers
at even stack offsets.
The remaining legality requirements are already checked when the
register pairs are formed.
The reordering algorithm primarily works by determining the parity of
the lowest ZPR spill offset. If the offset is odd, it places one
unpaired ZPR spill first so that subsequent register pairs begin at even
offsets.
Windows is not supported by this reordering algorithm for now, to keep
this change minimal.
New tests have been added to sve-callee-save-restore-pairs.ll to test
the reordering algorithm.

This handles 2 additional cases when Start < RHS:

* Start == Stride and Start == Stride -1.
The patch includes a mechanical change to move up the existing
MayAddOverflow with comments, and clarifies the name to

The current check in `emitLabel()` is too strict. Inside a PR, there
cannot be no other external visible label. However, temporary labels
which are used e.g. for calculating offsets can be emitted. A situation
in which this occurs is the emission of the DWARF EH tables, in which a
temporary symbol (with an empty name) is emitted at the begin of the
table, causing an error message. This change limits the error to
non-temporary labels.

[lldb] Move most PDB shell tests to NativePDB (#222370)
I plan to remove the DIA PDB plugin before the 24 release - we switched
the default to the native one in 22. To avoid losing test coverage in
the process, this moves the SymbolFile/PDB tests to
SymbolFile/NativePDB. They were already running with both plugins. In
some cases, we set `env LLDB_USE_NATIVE_PDB_READER=1`, which I flipped.
The remaining shell tests are:
- `func-symbols.test`: Has a duplicate in NativePDB with different
checks, because the two plugins don't create identical types (see
comment in test)
- `udt-layout.test`: Also has a duplicate with different checks, because
the two plugins show the base classes in a different order.
Other than that, there's also a [unittest for
PDB](https://github.com/llvm/llvm-project/blob/2de38b4861ed4a7be7ddd42fc803e91d1fe81b14/lldb/unittests/SymbolFile/PDB/SymbolFilePDBTests.cpp).
I'm not sure what we should do about it. Looking over the tests there,
most of these are already covered by the shell tests.

[Hexagon] Lower vreduce(min|max)((imum)?) (#211898)
Add custom lowering for VECREDUCE_FMIN/FMAX/FMINIMUM/FMAXIMUM on HVX
float vector types. The target-independent default expansion reduces
these pairwise using the hardware min/max instruction directly, which
does not implement IEEE-754 NaN-propagation semantics: a NaN in the
input can silently corrupt the reduction result, and an all-NaN input
produces a non-NaN value instead of NaN.
The custom lowering strips NaN elements to the appropriate neutral value
(+/-Inf) before the pairwise tree reduction so a NaN can't corrupt other
lanes, then fixes up the scalar result to NaN if every input element was
NaN.
FMINNUM/FMAXNUM on HVX vector types get the same treatment: NaN operands
are replaced with the neutral value before delegating to the hardware
min/max, with a fixup to restore NaN when both operands were NaN (per
llvm.minnum/maxnum semantics).

Both should be half-word aligned. However, testing revealed that both
can end up on odd addresses, which leads to relocation errors. Fix is to
change the alignment.

[OpenMP] Avoid use of ConstantExpr::getSizeOf() (#222662)
Support for this will be dropped as part of the ptradd migration.
Replace with a constant size.
While I'm touching the code anyway, I also simplified the size
calculation a bit. It's computing both the size in bytes and in
elements. Avoid doing an unnecessary division followed by multiply for
the size in bytes.

[llvm-ar][GOFF] Implement symbol attributes for GOFF archives (#214528)
z/OS archive symbol table entries contain a 32-bit attribute word
alongside each member offset.
The low three bits encode:
```
bit 2 (0x4): 64-bit addressing (AMODE 64)
bit 1 (0x2): XPLink calling convention
bit 0 (0x1): Writable Static Area (WSA)
```
Previously in e2c8fa0, llvm-ar wrote zero for these attributes. This
patch reads them from GOFF ESD
records and stores them in a SymbolAttrs vector parallel to the existing
Symbols vector in MemberData
to emit the correct word per symbol.
These attributes are tested using `llvm-nm --print-armap` implemented in
#214527 within the LIT test.

[SystemZ][z/OS] Fix "relative immediate relocation section mismatch" (#222437)
Constants should go inside the text section, but this is not explicitly
coded. In the test case, the EH table is generated into a PR section.
Then the constant pool of function `fn_with_const_pool()` is emitted,
which goes into the PR section of the EH table instead of the code
section. When the constant is later referenced in the code, the relative
offset cannot be calculated because different sections are involved.
The fix is to explicitly return the text section for constants.

[CodeView] Read and dump `S_ASSOCIATION` (#221034)
`S_ASSOCIATION` associates one symbol with another one. Right now, it's
only used for coroutines. The `get_associatedSymbol*` functions from
[`IDiaSymbol8`](https://learn.microsoft.com/en-us/visualstudio/debugger/debug-interface-access/idiasymbol8)
use this record. I'm not sure if the VS debugger uses this at all.
The symbol value was added earlier, but we weren't able to read/write
it. Also, lld would remove it when linking, as it didn't know if it
contained type indices.
This PR adds support for that. It's only visible in llvm-pdbutil where
we can dump it and roundtrip through yaml. I checked that it uses the
correct format when used with the DIA dump sample.
The coroutine kind is still missing. It's contained in the flags of an
`S_FRAMEPROC`. But it'd like to wait for #215887 which touches the flags
in YAML.

[SLP][AMDGPU] Fix test to actually exercise count-check condition (#222022)
The gfx906 RUN lines in `inst-count-heuristic.ll` never exercised the

This patch converts the test kernel from `i32` to `i16` elements so the
heuristic's `getVectorFactor() == 2` gate is actually reachable on
gfx906, and adds a `-slp-inst-count-check=false` RUN line to cover the
non-default behavior.

[SLP][AMDGPU] Fix load-address typo in v4f16 combine tests (#222112)
Patch addresses issue where tests are not performing 4 contiguous
elements load/store chain as intended.
- Correcting both typos (`%tmp6` vs. `%tmp10`) so each function
represents a contiguous 4-element chain.
- `copysign_combine_v4f16` and `canonicalize_combine_v4f16` now
vectorize identically on `GFX8` and `GFX9`.
- Adding `canonicalize_combine_v4f16_noncontiguous`, to preserve
existing test coverage, so the non-contiguous-gather path isn't silently
dropped.

[NFC][SemaHLSL][CGHLSL] Move semantic classification to common `HLSL/SemanticSignatures` (#218058)
Updates SemaHLSL and CGHLSL to not use stringref compares to distinguish
semantics and converts them to a common `SemanticKind` enum.
Further, it moves the classification of valid shader stages into a
common table to denote where a semantic is interpreted and how it is
used to to derive if it is valid.
This also updates tests that were using invalid semantic constructs to
use corrected versions.
This is a pre-req for the signature packing issues (#205875, etc) and
#189765

[MLIR][XeGPU] Lower arith.truncf wider than one xevm.truncf group (#217130)
`xevm.truncf` lowers to device builtins that convert exactly 16 f16/bf16
elements
per call, so `TruncfToXeVMPattern` only matched a 16-element source. A
workgroup-level mxfp GEMM that quantizes A in the kernel produces a
wider one,
which nothing else lowers, so the module failed to build:
%r = arith.truncf %a : vector<32xbf16> to vector<32xf4E2M1FN>
// cannot be converted to LLVM IR: missing
`LLVMTranslationDialectInterface`
// registration ... for op: arith.truncf
Convert a whole number of groups at a time instead: slice the source
into
16-element groups, emit one `xevm.truncf` per group, and concatenate the
packed
results before the final bitcast. A source of exactly one group takes
the original
path with unchanged code, and a source that is not a whole number of
groups is
still left to the regular arith-to-LLVM path.
`arith.extf` carries the same restriction on its result, but no wider
case has come
up, so it is left as is.

[mlir-translate] Add structured translation entry point (#222623)
Please read: [RFC: Embeddable LLVM tool drivers for long-lived
hosts](https://discourse.llvm.org/t/rfc-embeddable-llvm-tool-drivers-for-long-lived-hosts/91754)
and the [MLIR
section](https://discourse.llvm.org/t/rfc-embeddable-llvm-tool-drivers-for-long-lived-hosts/91754#p-367966-mlir-13).
`mlir-opt` already separates its standalone command-line frontend from
its reusable implementation:
```text
command-line parsing
↓
MlirOptMainConfig
↓
MlirOptMain(input buffer, output stream, registry, config)
```
`mlir-translate` currently combines those responsibilities inside
`mlirTranslateMain(int argc, char **argv, ...)`: it registers and parses
its command-line options, opens the input and output files, and then
performs the translations.
This patch applies the existing mlir-opt structure to mlir-translate. It
extracts the MLIR translation executor behind a structured overload
accepting an input buffer, output stream, selected Translation objects
and an MlirTranslateMainConfig. The existing command-line entry point
continues to parse the same options and delegates to the new overload,
so its command-line behaviour remains unchanged.
Separating parsing from execution is useful for any application
embedding MLIR. Such an application already has its input, output and
selected translation, and should not be required to install another
command-line frontend into the process merely to call MLIRTranslateLib.
[WasmBolt](https://github.com/anutosh491/WasmBolt)(try
[here](https://anutosh21.github.io/WasmBolt/)) is one concrete consumer.
It runs `mlir-opt`, `opt`, `llc`, Clang and LLD inside one long-lived
browser-hosted LLVM process. Calling the complete `mlir-opt` and
`mlir-translate` command-line frontends in that process causes common
options such as `-o` to be registered twice in LLVM's process-global
command-line registry.
```
mlir-translate: CommandLine Error: Option 'o' registered more than once!
LLVM ERROR: inconsistency in registered CommandLine options
```
The structured entry point allows WasmBolt to invoke the actual MLIR
translation operation without registering another command-line frontend.
This is needed to continue naturally from the MLIR LLVM dialect to LLVM
IR inside the same compiler session.
Add a simple test where the test register its own `-o` option first,
then runs two translations through the new API and checks the output.
This confirms that the translation path works without touching the
command-line parser. **Can Improve it a bit if it looks too informal.**

This enables developers and CI pipelines to measure source-level and
MC/DC coverage directly on hermetic tests in full-build configurations
without relying on the host C library.
Updated add_libc_hermetic in LLVMLibCTestRules.cmake to link hermetic
tests with -noprofilelib, -u__llvm_profile_runtime, and compiler-rt's
profiling library. Replaced internal entrypoint objects in
link_object_files with public entrypoint objects for the C functions
referenced by libclang_rt.profile.a.
Added calloc and __errno_location to HermeticTestUtils.cpp to satisfy
remaining freestanding profiling runtime dependencies. Updated
libc/docs/dev/code_coverage.md with full-build instructions.

[lldb] Expose vector registers through SBValue (#220707)
This is adding GDB remote vector register support.
- Build exact Clang types from parsed vector metadata.
- Use native Clang vectors where valid and arrays where required to
preserve exact layouts.
- Support nested, pointer, boolean, and non-power-of-two vectors.
- Expose vector lanes through `SBValue` children and expression paths.
- Handle typed vector data correctly across target byte orders.
- Add builder, SB API, layout, cache, and big-endian tests.
Example:
```
vector = frame.FindRegister("v0")
vector.GetNumChildren() # 4
vector.GetChildAtIndex(2).GetValue() # "3.5"
vector.GetValueForExpressionPath("[2]").GetValue() # "3.5"
v = frame.FindRegister("v0")
print([v.GetChildAtIndex(i).GetValue()
for i in range(v.GetNumChildren())])
# ['1.5', '2.5', '3.5', '4.5']
```
Structured `register read` output is added separately in patch 5.

[clang] Support DecompositionDecl in -ast-print (#221711)
`DeclPrinter` had no `VisitDecompositionDecl`, so `auto [a, b] = get();`
printed as `auto = get();`, silently dropping the binding list (worse
at namespace scope, where it also produced a stray empty statement per
binding).
Add `DeclPrinter::VisitDecompositionDecl`, printing the full
`type [bindings] = init;` form for all three decomposition kinds
(aggregate/member, array, tuple-like), matching what `VisitVarDecl` does
for an ordinary declaration. Specifier and initializer printing is
shared between the two via two helpers (`printVarDeclSpecifiers`,
`printVarInitializer`) so they can't drift apart.
Each binding prints correctly, including a pack's leading `...` and
per-binding attributes. `BindingDecls` are skipped when walking a
`DeclContext` directly, since each is already printed as part of its
`DecompositionDecl;` a decomposition declaration is likewise kept out of
the tag-declaration grouping in `VisitDeclContext`, which would
otherwise merge it into a preceding `struct S { ... } obj;`.

`find_package(Clang ...)`, which is deliberately not `REQUIRED` and is
expected to tolerate an unavailable package — but a *half-generated*
package is a hard error rather than a "not found". Concretely,
`-DLLVM_ENABLE_PROJECTS=flang -DLLVM_ENABLE_RUNTIMES=flang-rt` fails at
`runtimes-configure`, which is the configuration premerge uses for
flang-rt changes.
This patch guards the include the same way the export itself is guarded,
so a dependency-only project generates a config without a dangling
include. The install-tree path already handles this through
`get_config_exports_includes()`; only the build-tree path was missed.
MLIR has the same defect and is fixed here too. It is currently latent
only because `runtimes/CMakeLists.txt` calls `find_package(Clang)` and
not `find_package(MLIR)`; a `find_package(MLIR)` against a
dependency-only build tree fails identically at `MLIRConfig.cmake:33`.

[TOSA] Add pass to sanitize gather/scatter indices (#221200)
Add new TosaGatherScatterHardeningPass TOSA pass to clamp indices before
they are fed to a tosa.gather or tosa.scatter unless a suitable clamp
sequence already exists. This enables avoiding out-of-bounds accesses on
untrusted indices in tosa.gather and tosa.scatter lowering.
The pass fails if the dimension indexed by the indices tensor of any of
the tosa.gather or tosa.scatter is dynamic. The pass supports EXT-INT64
by using the same element type in the clamp min/max sequence as the
indices tensor. In case the indexed dimension is bigger than can be
represented in the element type bitwidth the maximum value in that
bitwidth is used.

Log Message:
-----------
[LoopIdiom] Recognize the ctlz/cttz idiom when the input is known non-zero (#222373)
LoopIdiomRecognize converts a shift-until-zero loop to `ctlz`/`cttz`.
When the loop uses the count outside the loop, it needs a zero check of
the input before the loop. Without the check, the inputs 0 and 1 give
the same count. The recognizer stops when the check is not present.
The check is not necessary when the input is known non-zero. InstCombine
can remove the check for such inputs. Then the recognizer does not
convert the loop. This happens in `sbc_calc_scalefactors` from ffmpeg
with #222334: the input is an or reduction that starts at 32768, so it
is never zero, and the loop stays a loop.
This patch makes the recognizer accept a known non-zero input in place
of the zero check. The conversion is exact in this case.
`ctlz-loop.ll` in PhaseOrdering had a FIXME for a loop over `abs(n)`.
The recognizer now converts that loop too.
For the ffmpeg case, `isKnownNonZero` must also see that an or
recurrence with a non-zero start is non-zero. That change goes into
#222334.
